Black rhinoceros or hook-lipped rhinoceros.

What would you do if walking through the park you suddenly find one of the largest animals on Earth, it observed you?

As well, are various options:

a) act as if you have not seen and still waiting for the rhino strolling act like you.
b) running away and screaming: Help, save me!!
c) use of animal psychology and go without fear and give it a hug.

Well, even if you're confused, I'll tell you the three answers are good. The black rhinoceros, though an animal with a formidable horn and incredible strength, is classified as one of the more docile animals of Africa. In fact, if you become familiar with it, you can even feed him by hand.

Many tourists who find these animals in the wild, and can approach and even touch them and take a picture. Do you think you could do with an elephant? Or a hippo? .... I assure you not.

The black rhino is a bit smaller than its brother the white rhino. Its weight rarely exceeds 1500 kg (3300 lb), height is 1.6 meters (6 ft) to the cross and long reach to 3.5 meters (15 ft). Its color is a dark gray and then one of their names. The other name by which we know is "hooked-lipped rhinoceros". This is because, unlike the white rhino, which has the upper lip very broad and straight, the black rhino has it finished in peak form. This will help to eat little bushes and tall trees. But lip white rhino is more to pasture ... as cows do.

Currently, the black rhino is in danger of extinction. During the '60s, was massacred by the bastards ... gentlemen who hunted them to boast a beautiful trophy animal. In addition, its horn is coveted by oriental medicine and benefits attributed to certain properties in order. By luck and hard work, gradually the number of individuals increases and 4500, increased to 5,000 in the last census.

Saiga antelope or Saiga tatarica.

This animal, a little disproportionate, is the protagonist of one of the largest migrations that occur throughout the animal world. A migration comparable to that produced by millions of wildebeest and zebras in central Africa.

Is an animal the size of a sheep, a herbivore that feeds on plants harder, poor and stale to be found in the Russian steppe. About 50 kg in weight, 70 cm in height and more than 1 meter long. The most notable feature is his nose: broad, long and mobile, similar to tapirs. The nose is a perfect adaptation to climate. In winter heats the air before it is introduced into the lungs. However, in summer, is able to filter and retain windblown dust from the steppes. Another adaptation to cold is its coat, tan and short in summer, but long, thick and white in winter. A survivor of the last glaciation.

Among their predators are wolves, foxes, birds of prey and large prey.

The last migration are being more and more reduced, are currently believed to not more than 30,000 individuals. Animals passing through areas that create the effect funnel with a width less than 5 km. Bridges that connect two areas not yet occupied by man.

Apart from the destruction of their habitat, this animal is being hunted out of control to get their horns. Horns are an ingredient that has a certain value in traditional Chinese medicine, already the horns are replacing other ingredient even more scarce, rhino horn.

He is currently in critical danger of extinction.

Pygmy tarsier.

After viewing the Long-eared Jerboa, an animal that awakens in us a tender feeling, I decided to go with another animal just as endearing and tender that the Jerboa: Pygmy tarsier.

This small animal as big eyes, was believed extinct for years, relieving the superstitious inhabitants of Sulawesi. Indonesians in this zone they had no problem getting rid of them, hunt them and kill them because the figure of a tarsier called forth from them prejudices and superstitions of an animal identified with "animal unlucky". Extinct for 80 years, suddenly appeared while a villager a plague of rats exterminated in the village fences. Scientists discovered by surprise that Pygmies had not disappeared, the little animal died, there was a rat amorphous, it the extinct tarsier. This promoted the search for new specimens, which were found and were able to study and help them survive until new born individuals.

Currently this animal is in danger of extinction, but it seems that slowly, and through the efforts of various institutions, their numbers are increasing.

Besides its size (10 cm (4 in) + furry tail and less than 60 g weight (2 ounce)), the Pygmy tarsier has characteristics that make it unique. Here are the most curious:
1 - The pygmy tarsier, has a communication system similar to that of other tarsiers, but its voice is so acute that we can not hear. It communicates with frequencies of 90 khz. We can not hear sounds with frequencies higher than 20 kHz. In fact, experts thought it was dumb until they discovered this.
2 - Another unique feature of this little animal, is its diet. It is the only primate that has a carnivorous diet extricta. Although they look seem to eat little fruit and grass, the tarsier is a fearless hunter, is insectivorous, but some claim it is able to hunt birds and small reptiles clueless.

3 - Is the animal with the largest eyes in relation to its weight and size. And these huge eyes, help you move between the dark because they are nocturnal.

Long-eared Jerboa.

Have you ever seen an animal with a face so candid? Surely not. Well, this little rodent is the  Long-eared Jerboa (sesudo name) or Euchoreutes naso.

This small, nocturnal creature with pig nose and ears of Dumbo, lives, and with difficulty, in the inhospitable Gobi Desert in Mongolia. A desert known for sudden changes of temperature extremes. Well, in this poor habitat live Long-eared Jerboa.

Their long ears are the perfect tool to dilute body heat by the fine blood vessels that run through. Jerbo is  higher animal ears worldwide, proportionally speaking, of course. Its body is not larger than 3,5 in (9 cm) in length, minus the tail, then his ears are 2,3 in (6 cm). It is as if we had ears until we reach our ass (what we would hear everything).

Another feature of this small rodent and insect hunter, are its legs. Their legs are long and strong (always speaking in proportion) enable you to "large" jumps to escape their natural depredores.

Now, I feel myself dramatic and serious, but sometimes there is no alternative. This little animal is in real danger of extinction. Nocturnal, it is a strange animal, and by small zoos breeding projects, there is little hope to avoid their disappearance.

I have a video that was made by the Zoological Society of London with the intention to denounce the elimination of this beautiful little animal: The first video eared jerboa.

Cantor's giant softshell turtle

Their taxonomic name is (Pelochelys cantorii) and commonly called Cantor's giant softshell turtle or Asian giant softshell turtle. Is a turtle a little "freak" ... as we all know, the characteristic of all turtle is its shell, which is the union of bony plates covered with hard plates together to give strength and rigidity and simultaneously protects the turtle from possible predators.

But the turtle has a soft shell (I think I'm a bit of creeps), it does not serves as a hard shell to the turtle because there are few predators of a turtle that can measure 2 meters long and weigh 50 kg. Perhaps the man is the worst predator.
Also, this softshell turtle is usually under the sand or mud to protect themselves from predators.

But not only that, we know that this turtle is ferocious (considering how ferocious can be a turtle) and has a strong bite. It is an efficient carnivore, and its prey are fish, molluscs, crustaceans and other smaller amphibians. But due to its size and bite, would be able to pluck one finger.

Another peculiarity of this animal is that the experts considered extinct, but were rediscovered in 2007, and since then has been an ambitious recovery program that has been successful. We can not say that is no longer in danger of extinction, but it is recovering.

Dhole, Cuon Alpinus.

In India there are bears, leopards and tigers. Three big predators that at the same time have a common predator and not humans. The most dangerous animal of South Asia is the Dhole, also called  Asiatic wild dog or Indian wild dog.

Do not rely on appearance similar to a clever but harmless fox, Dhole is a predator  bold and is able to hunt large and dangerous animals such as water buffalo that easily weigh 1 ton.

It is said that this wonderful animal is the predator king of India, and that are more dangerous than the tigers. In fact, we know that in many cases the Dholes attack and kills  tigers. Those tigers are defending hedging its bets with a tree or a rock are the ones most likely to survive. But the tigers run off are bitten and bled and fall prey depletion of cuones. While it is true that on many occasions some Cuon alpinus falls victim to the claws of the tiger.
But if someone Dhole is hurt when hunting , this individual is protected and cared for the herd. And they are very social animals. And herd are numerous, several individuals, 20 or more individuals.
Dhole herds can also steal a leopard prey, while the leopards can kill them if they are found alone or in pairs.

Unlike herd of wolves, herds of several females have procreative cuon. They are more social and less territorial than wolf packs and unlike these, is said not to live in packs, but form clans. The difference of this technique is hunting.

Well, it's like a medium sized dog, like a coyote, reddish like a fox and a short snout shorter than other species of the family Canidae. Weighs no more than 20 kg. His body is well proportioned, its members are moderately long, and proportional chest. They have great leaping ability and to make great leaps, up to 3.5 m high and 6.5 m long ... quite an athlete.

It is endangered because of the elimination of habitat and prey. Besides competing directly with men.

The Cuban solenodon or almiqui of Cuba

The Cuban solenodon or almiqui of Cuba is a very curious, is an animal that was considered extinct since 1970 and was rediscovered a few years later in a remote place of the island of Cuba ... is an animal that is in real danger of extinction and for people who love animals, we were happy to know it was not extinguished.

The animal that we can remember the shrew or a hedgehog, a little larger than a rat (up to 80 cm long). It has an elongated snout and is also an omnivorous predator. It has tiny eyes, long snout with small but sharp teeth and also enters the exclusive group of venomous mammals, along with other mammals as exotic as the Platypus and the Echidna. By the way, so my assessment is an animal that could catalog in the group of the most ugly.

Being omnivorous, this animal can feed on plant, fruits or roots, but also of invertebrates and other animals of considerable size for it, as birds, frogs, reptiles and even rats ... because it is a gallant and brave predator and has an effective poison.
Experts are trying to increase the population of this animal, but it is really difficult for two reasons.

The first reason is that unlike other animals of similar size, only has one litter per year of between 1 and 3 individuals.

Second reason, it has been discovered that these animals when raised in captivity conditions become more aggressive (and which are solitary animals), and are not immune to its own venom, therefore, when fighting often occur including low in one or two individuals.

Finally, humans have great capacity to destroy, but we also have the great ability to help a species recover.

Musk deer.

If we see skull of this animal, one can think that belongs to a predator of large tusks. Remember the saber-toothed tiger. But really it isn´t a carnivorous hunter, not a key animal in the trachea fangs of its prey, does not infringe fatal bites. This skull is that of a peaceful vegetarian: musk deer.

  In contrast to other deer, the stags antlers do not grow, but two huge tusks that give it the appearance of deer-vampire (a term invented by me). Well, these tusks grow throughout his life and apparently, its function is the same as that of other deer antlers ... size does matter.

Another feature of the musk deer is that unlike other deer, he lives as a couple.

There are several species and they think they are smarter than other musk deer do not.

Finally, perhaps the most significant trait. We note that the name given to this deer is due to their body scent of musk. A strong sweet smell, which contains pheromones and is used in some perfumes. In fact, there is a very nice story about this feature:

When the deer began to feed himself, he noticed the strong scent of musk. He wondered, perplexed, where he came fresh and enveloping perfume.

Began to investigate its source everywhere, it was impossible to escape him, but so was to know its origin. The animal became more and more curious. No truce, was still looking for the source of the smell so intense. He sought constantly, day and night, the victim of an obsession that did nothing but increase. So the years passed. Hart lived moments of great weakness, of unspeakable anguish, deep grief. did not get your search results.

Fifteenth century engraving

Musk deer aged and died. "I never knew that intoxicating perfume came from himself."

This musk-containing glands in the snout. But there is also another ingredient that it produces and which also becomes a target for hunters. It is through the flesh, not by the need to eat. It is hunted by a glandular substance is used as "drug" for athletes. Is prohibited and is considered doping.

Thanks to its smell, its doping substance, in fewer habitat (if I have not said is just east of Asia), its conservation is threatened.

Purple Frog, Indian Purple Frog or Pignose Frog

It's a frog recently known exactly since 2003 and between that and the few specimens that have been found, little is known of it. It is known as the Purple Frog (Nasikabatrachus sahyadrensis means nosed frog Sahyadri, India.)

It is probably one of the ugliest frogs, well not only of frogs, the entire animal kingdom. Compared to other frogs, this frog is purple and will never be a prince ... but the princess kissed and kissed him (if she is brave).

It measures about 7 cm long, has a pointed nose and small eyes together. His body is plump, purple and muscular, with ossified bones that allow you to dig on land. Lives underground and only rises to the superfecie to mate during the monsoon season. By the way, makes a funny noise, it has nothing to do with the croack typical of other frogs. I advise you to see this video.

This small frog is endangered and possibly in a few years only see in zoos. The purple frog is threatened by habitat loss due to coffee, ginger and cardamom. All the pity.

Emperor Butterfly.

The emperor butterfly, as its name suggests, is a butterfly that is above the others, is the species name of a butterfly is considered one of the largest in the world. Rather .... THE GREATEST.

Emperor Butterfly (Thysania Agrippina), is also known as bird-winged butterfly, white devil, butterfly ghost, witch big gray. And it is certainly larger than many birds.

Is large, with a wingspan of up to 35 cm. And despite his major and his royal name, is an animal that is endangered due to destruction of their
natural habitat.
It is a moth of powerful flight, easily confused with a bat or a bird. A
often close to the houses, attracted by the lights. Some superstitious people ascribe bad omen.

Sorry I can not show more pictures.

Giant golden-crowned flying fox, Acerodon jubatus

The Giant golden-crowned flying fox (Acerodon jubatus) is the largest known bat. Can reach up to 1.70 meters wingspan, slightly less than the Pteropus vampyrus and weighs 1.5 kg.
This curious animal is endemic to the Philippines, and is in danger of extinction as they hunt for years to eat its flesh. Another element is the deforestation of their habitat.

It is a nocturnal mammal and their diet is not the blood of their victims, but fruit, flowers, nectar ... Helps disperse the seeds when defecating and can live to 15 years.

Unlike other bats, flying foxes and echolocating filipino are not large eyes which allow them to see in the dark of the Philippine jungle.

The White-faced Saki (Pithecia pithecia)

The White-faced Saki (Pithecia pithecia), also known as the Guianan Saki and the Golden-faced Saki, is a species of saki monkey, a type of New World monkey, found in Brazil, French Guiana, Guyana, Suriname, and Venezuela. This species lives in the understory and lower canopy of the forest, feeding mostly on fruits, but also eating nuts, seeds, and insects. Sakis are omnivores. They eat fruits, leaves, flowers, insects, and small vertebrates, such as rodents and bats.
Sakis are small-sized monkeys with long, bushy tails. Their furry, rough skin is black, grey or reddish-brown in color depending upon the species. The faces of some species are naked, but their head is hooded with fur. Their bodies are adapted to life in the trees, with strong hind legs allowing them to make far jumps. Sakis reach a length of 30 to 50 cm, with a tail just as long, and weigh up to 2 kg.
Sakis live in family federations, which consist of parents and their offspring, with mated pairs usually forming lifelong pair bonds. They are territorial animals, defending their territory in relation to other families. Sakis know a set of communication possibilities: while shrill cries or bird-like twitter serves as a connection among family members, a loud roar serves to warn other animals off their territory.
Whilst not an endangered species, Sakis and other South American primates are vulnerable due to the destruction of their habitat by humans. They are also hunted for food and for the pet trade.

The Leopard seal eats persons when it is hungry, I am sure.

The Leopard seal (Hydrurga leptonyx) is the second largest species of seal in the Antarctic (after the Southern Elephant Seal), and is near the top of the Antarctic food chain. It is most common in the southern hemisphere along the coast of Antarctica and on most sub-Antarctic islands. It can live twenty-six years, possibly more.[3] Orcas are the only natural predators of leopard seals.

The leopard seal is large and muscular, with a dark grey back and light grey on its stomach. Its throat is whitish with the black spots that give the seal its common name. Females are generally slightly larger than the males on average.[4] The bulls are generally 2.5 m (8.2 ft) to 3.2 m (10.5 ft) and weigh between 200 kg (441 lb) and 453.5 kg (1,000 lb), while cows are between 2.4 meters (7.9 feet) and 3.4 meters (11.2 feet) in length and weigh between 225 kg (496 lb) and 591 kg (1,303 lb). [5]

Compared to most phocids, the Leopard seal is highly evolved for its role as keystone predator. Although it is a true seal and swims with its hind limbs, it has powerful and highly developed forelimbs similar to sea lions, giving it a similar maneuverability, a classic example of convergent evolution.
In 2003, a leopard seal dragged a snorkeling biologist underwater to her death in what was identified as the first known human fatality from a leopard seal.[7] However, numerous examples of aggressive behavior, stalking, and attacks on humans had been previously documented.[7] The leopard seal has previously shown a particular predilection for attacking the black, torpedo-shaped pontoons of rigid inflatable boats, necessitating that researchers equip their craft with special protective guards to prevent them from being punctured. The leopard seal has also been known to snap at people's feet through holes in the ice.

This seal is dangerous.

Tasmanian Tiger Extinction Mystery.

The Tasmanian tiger or Thylacine was by far the largest carnivorous marsupial of recent times. Its overall appearance is very canid-like. Total body length is around 1 meter. The tail length is around 50-65 cm. The tail itself is very thick close to the body and quickly tapers to a point. It is around 60 cm in height at the shoulder. The upper body is brownish/grey with a pale underside. There are 13-19 black vertical stripes that run from the mid-back to the base of the tail. The face is grey with white markings around the eyes. The fur is short and thick. Their skull has a length of 22 cm and the dental formula is: i 4/3, c 1/1, pm 3/3, m 4/4. Tasmanian tiger's long canines, shearing premolars, and grinding molars, all of which are quite similar to those of dogs. The feet are padded and leave a five-toed print. The females pouch is located by her tail and has a fold of skin covering the four mammae.
Tasmanian tigers lived only on the island of Tasmania in recent history, but fossil record shows that it was also found in New Guinea and Australia as recently as 3000 years ago. Competition with dogs brought by aborigines eliminated it in Australia and New Guinea. These dogs ran wild, becoming the dingo, which entirely filled its niche. A large population survived on Tasmania, where there are no dingoes. But when the Europeans arrived and settled in Australia and Tasmania the Tasmanian tiger was thought to be a livestock killer, especially when sheep were introduced in 1824. This was never substantiated, but because of this misconception the privet sector and the government hunted the Tasmanian tiger from 1830-1909 for bounty. In 1830, the Van Diemens Land Company, a pastoral company in Northwest Tasmania, introduces the first bounty on the Tasmanian tiger, claiming that the animal attacked sheep.

Extinction may not be forever after all; so hope the Australian scientists behind an ambitious project to clone the extinct Tasmanian tiger.
The project to bring the Tasmanian tiger back from extinction began in 1999 when Australian Museum scientists extracted DNA from an ethanol-preserved female pup in its collection.
We will see in a future if it is possible it to come back to the life, or as it has been said in several mass media, it is possible that the wolf marsupial is living , hidden from the man.Look that beautiful
